Fact sheet for the safe use of anaesthetic equipment & prevention of cross infection, Version 1.0 (June 2015)
The SA Health Reprocessing Policy Directive aims to ensure appropriate governance systems are in place; regular audits occur, and all staff involved in the use and reprocessing of reusable medical devices consistently adhere to the recommendations in the relevant local health network, state, national and international standards and guidelines, in particular AS/NZS 4187:2014 – Reprocessing of reusable of medical devices in health service organisations, and the National Safety and Quality Health Service Standards.
Items marked "single-use only" (PDF 81KB) or with the symbol must not be reprocessed.
Items labelled "single-patient use", can be re-used on the same patient after reprocessing according to the manufacturer’s instructions.
Currently the regulatory requirements for the reprocessing of medical devices labelled as "single use" are covered by:
SA Health also has a fact sheet on the Safe Use of Anaesthetic Equipment and Prevention of Cross Infection (PDF 108KB) which outlines the infection control requirements for reprocessing of these specific items, several of which may be labelled as "single use" or "single patient use".
Cleaning is the essential first step for any form of reprocessing:
The item and its intended use determine the level of reprocessing required. The manufacturer’s instructions, health service policy, applicable guidelines and standards should all be taken into consideration when determining the most appropriate process. The "Spaulding classification" is often used to assess reprocessing requirements1 and is summarised in the:
Application: Entry or penetration into sterile tissue, body cavity or bloodstream
Application: Contact with intact mucous membranes or non-intact skin
Process: Sterilisation is preferred where possible.If sterilisation is not possible then high-level chemical disinfection is required
Application: Clean as necessary with detergent and water (disinfect after cleaning as required)
Process: Contact with intact skin only
Semi-critical items, such as endoscopes, laryngoscopes and ultrasound probes/transducers that are used in body cavities or during surgery should ideally be sterilised, but many of these equipment items are heat sensitive and therefore require high-level disinfection to render them safe to use on another patient. There are many different automated systems available for high-level disinfection, including automated endoscope reprocessors, and specific systems for high-level disinfection of ultrasound probes.
Examples of effective high-level disinfectants include:
There are disadvantages with the use of each of these chemicals, such as occupational exposure concerns and materials compatibility issues. For a summary of these issues see the CDC Guideline for Disinfection and Sterilization in Healthcare Facilities, 2008 (Table 5, page 110).
Ortho-phthalaldehyde (OPA) has largely replaced the use of glutaraldehyde in most healthcare facilities due to its superior microbicidal properties, shorter immersion time and safer risk profile. SA Health has developed a fact sheet on the safe use of OPA (PDF 52KB) which highlights some of the risks and procedures that need to be followed.
For detailed information on training and reprocessing of endoscopic devices, see the Gastroenterological Society of Australia Infection Control in Endoscopy Guidelines.
For detailed information on the quality assurance of endoscope reprocessing, see the SA Health Microbiological Testing of Endoscopes Clinical Guideline (PDF 420KB).
Compliance with AS/NZ 4187:2014 can be assessed by using an audit tool (PDF 699KB) developed by Southern Adelaide Local Health Network (SALHN). A word version of the audit tool is available on request by contacting SA Health's Infection Control Service.
The NSW Clinical Excellence Commission has developed a suite of audit tools and quality management resources for monitoring compliance with reprocessing standards.
All healthcare providers who reprocess reusable medical devices are responsible for meeting appropriate national standards of safety and quality in infection control. To support compliance with accreditation requirements the Australian Commission on Safety and Quality in Health Care provide standards and audit tools for health facilities.
This includes office-based and smaller medical practices where the above tool may not be suitable.
All healthcare providers that use ultrasound transducers, standard of practice for reprocessing ultrasound transducers can be sources from:
The SA Health Reprocessing of Reusable Medical Devices Governance Committee (SARC) is a group of health professionals from metropolitan and country hospitals who work collaboratively to advocate for the best practice in sterilisation and reprocessing of reusable medical devices, giving oversight of the implementation of AS/NZ 4187:2014 across SA Health facilities.
The SARC is also a forum for health professionals to network, raise issues and seek advice from other members' knowledge and experience. To share ideas or seek reprocessing advice, contact the Sterilising and Reprocessing Medical Device Reprocessing State Coordinator.
